'WEEDER.

application filed November 17; 1925. Serial No; eat-7e;

This invention relates to agricultural impleinents, and has more particular reference to an improved device for removing Weeds from the ground preparatory to 'tilling 'and sowing seeds in the same. 7

The primary object. of the invention is t provide'a 'weederwhich'is extremely simple and "durable in construction as well as ef' ficient in operation. a I p Anotherobject -is-to provide a weeder embodying a transverse bar adapted to be caused to travel under the surface of the soil for uprooting and removing the weeds,

means being providedfor readily raising and lowering the weederbar for regulating the depth at which the same passes beneath the surface of the soil. 7 i c A further object is to provide a the above kind embodying weeder of and durable construction. s

for 'facilitating 'hitching of draft 1' animals l Other objects will become apparent as th'e' nature of the invention is better understood,

and the same consists in the novel-form,-

combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings andclaimed.

A pair of spaced'longitud-inaldraft tongues 7 are provided with rear ends extending across the transverse frame bars 5 andrigidly secured to the latter at equal distances from the longitudinal center'of the frame and thefends of the latter, and these draft tongues maybe equipped "with suitable devices such j-as wh'lp'p'le-trees thereto The'rear ends-or tlie draft tongues '7 project slightly rearwardly k beyond therear transverse frame bar 5 and have: crane 'versel'y" aligned bearings 8 'seci'1red tosthe un sidestheteof which is journal-led the A a frame of simple Figure 2v is a side elevational view thereof,

the frame bar 5 and pass over the adjacent portions of the draft tongues 7 so as toalso effectively brace the latter against lateral strains; Nuts 2a are threaded upon the end of the truss bars 22 at the outer sides of the brackets 23 so that said truss bars or rods 22 may be placed under proper tension.

'As clearly shown in Figures 1 and 3, one

of the brackets 23 is formed with-"an upwardly projecting extension in the form of a' rack segment '25 which is engagedby a su itablel-atch provided as g'enerallyind-icated-at 26'on-a longitudinally swinging hand lever 27 which is pivoted'upon the frame coincident with the axis" of the segment '25. The hand lever 27 has a link pivoted thereto adjacent its upper end as indicated at 28, and' theother end of this link is-pivoted as at 29 to'th'e forward upper end of a forwardly and upwardly projecting arm30 rigid with the intermediate portion of the axle 9. It is thus apparent that when the lever 27 is swung forwardly an upward pull may be exerted the arm 80' for causing the axle 9 to' turn in the bearings 8 and thereby bring the legs of the axle toward a vertical position. so as to elevate the weederbar 12 and the frame carrying the same. On the other hand, a rearward swinging movement of the lever 27 effects a rearward movement of-the legs of the axle 9 so that the frame and weeder bar are lowered. In this way the depth at which the weed-er bar 12 is positionedbeneath the surface of the soil may be regulated and the weeder bar may be completely held out of the ground when the device is not in use. 7 7

A suitable seat 31 may be supported upon the intermediate portion of the rear :frame bar 5 so as to accommodate an operator in proper position for manipulation of the lever 27 and for controlling the draft animals hitched to the draft tongues 7 In operation, the movement of the weeder is effected and the lever 27 is' then brought re'arwardly so as tocause lowering of the weeder bar'12 into engagement with the'grounds. Further low.-

J ering of the bar 12 results in passage of the I latterbelow the surfaceof the ground, and 7 when the same has reached the desired depth the'lever 27 is latched in position by engagement of the latch 26 with the segment 25.

I

Then the operation of the weeder is comported to the desired destination by swinging the lever 27 forwardly so as to exert an' upward pull upon the arm 30 and cause the axle to swing so that its legs move toward a verticalposition. This effects lifting of the frame and consequent lifting of the weeder bar 12 out of the soil or ground.

From the foregoing description it is believed that tl e'construction and operation as well as the advantages of the present invention will be readily understood. and appreci: ated by those skilled in the. art.
